To all whom it may concern:

Be it known that l, FRnonmoK H. Sonora, a citizen of the United States,residing at Lansdale, in the countyof Montgomery and State ofPennsylvania, have invented certain new and useful Improvements inGoncrete Road-Culverts, of which the following is a specification.

My invention consists of an improved concrete road culvert, such forexample as may be inserted under a road for draining water from one sideof the road to the other, how ever, it will be understood that myinvention may be used as a drain or culvert in other locations.

One object of my invention is to provide a drain or culvert which ismade up of reinforced concrete sections, said sections including pipeswhich have similar flanges at each end which are held together bycoupling sleeve sections, the ends of the pipe adjacentthe sides of theroad being secured within reinforced walls or plates in such manner asto prevent longitudinal movement.

Another object of my invention is to provide said walls with groovedholes through which concrete in a liquid state may be in.- serted sothat after said inserted concrete has set, it acts to lock the pipes tothe walls. A further object of my invention is to provide said wallswith an lar sleeves, preferably of metal, which Wlll serve as thesecuring means for a sign post or a post of any other description.

Another object of my invention is to so make the pipe sections that bothend flanges will be identical so that the pipes will roll in a straightpath so that they may be conveniently loaded in freight cars or stackedfor storage purposes.

Another object of my invention is to make the coupling sleeves insections and reinforce each section to prevent pressure from cracking orotherwise-injuring them.

A still further object of my invention is to provide said couplingsections with internal flanges which act as shoulders for the pipeflanges thereby keeping said pipes intheir proper position.

Another object of my invention is to so construct my improved drain thatit may be manufactured and sold at a comparatively low cost, and will bestrong and durable.

CONCRETE ROAD-CULVERT.

which will be described hereinafter, 1 attain 1n the following manner,reference being had to the accompanying drawings in which- Figure 1 is alongitudinal sectional elevation of my improved drain or culvert as itappears when extending transversely across a road. Fig. 2 is afragmentary perspect1ve view showing my improved buttress wall having apipe secured therein. Fig. 3 1s a sectional plan view taken on the linea-a of Fig. 2. Fig. 4: is a perspective view of one section of asectional coupling which employ to secure the ends of my improved p1pestogether. Fig. 5 is a face view of a modified form of my improvedbuttress wall or plate and made in interlocked sections, the body of thedrain pipe being shown in sec- .tion. Fig. 6 is an end view.

Referring to the drawings, 1 represents the roadbed having my improvedbuttress walls 2 and 3 located at opposite edge portions. Each of thesewalls is identical in construction and has a circular hole A whichextends entirely therethrough and of such diameter as to admit theflanged end 5 of an end pipe section 6. lhe wall forming said hole A isrecessed or grooved 'annularly as shown at 7, said groove beingpreferably located centrally between the outer and inner faces 8 and 9of the wall. A passageway 10 communicates with the groove 7, and extendsat an incline to and intersects the face 9 of the wall, said passageacting as a port hole for liquid cement as will hereinafter be morefully described. Each wall 2 and 3 is also reinforced by metallic wire11, preferably in a screened form, and the portions of said walls 2 and3 which are above the flanged ends of the end pipes 6, act to preventthe top or surface portion 12 of the road from washing or otherwisebreaking away adjacent the edges.

All of the flanges of the pipe sections are made identical, and theseflanges at positions intermediate the walls 2 and 3, are securedtogether by sectional coupling sleeves 13, one

of which is clearly shown in perspective in Fig. A.

Each of the sectionslf, comprising the coupling sleeves, is recessed at15 between its side surfaces to provide flanges 16 and 17 said flangesproviding shoulders against which the flanges of the pipe sectionsabutfi and it will be noted that the recess 15 1s 0 suficient width toreceive two abutting flanges of two pipe sections.

Each of the sections 14 of the coupling sleeves 13 is provided with asegmental reinforcing screen, preferably of metallic mm as shown at 18,thereby serving to resist pressure of the road and tenslon of the pipesections. The pipe sections also have reinforcing means as indicated at6. This means as illustrated consists of a metallic wire screen which isembedded throughout the length of the pipe and extendingcircumferentially thereof.

A metallic sleeve or bushing 19 extends through each of the walls 2 and3, and is preferably made angular as shown in Fig. 2. This bushing isgrooved intermediate its ends as shown at 20 (Fig. 3) and is embedded inthe concrete which forms said walls.

In assembling my improved drain, the intermediate ends of the pipesections are inclosed within the coupling sleeves, and the outer endflanges 5 are positioned within the holes 4 of the walls 2 and 3, sothat the outer ends of said pipe are substantially flush with the outerfaces 8 of the walls.

The width of the flanges 5 is such that the inner surfaces of .saidflanges coincide with the faces 21 of said grooves 7. When the flangesare so inserted, there is an opening which surrounds the body portion ofthe pipe section 6, and this opening is filled with cement through thepassages 10. In order to prevent the liquid cement from continuouslyrunning out of said opening, the opening may be banked by a few handsfull of mud to form a seal at the inner faces 9 of the wall, said sealacting to confine the liquid cement within the grooves 7 and the openingjust referred to. After this cement has set, it forms an interlock whichprevents the flanges 5 from pulling out through the portion of the holesthrough which they were inserted. In other words, it absolutelylocks theflanges 5.to the walls 2 and 3.

In the form of my invention shown in Figs. 5 and 6, the wall issubstantially identical with either of the walls 2 and 3 with theexception that it is made in sections as shown at 22 and 23, thesesections being tongued and grooved as shown at 24, the dividing lineextending in a substantial horizontal direction. In all other respectsthe construction isidentical'to the form above described, and I havetherefore given the same like reference numerals. I

In a drain or culvert constructed inaccordance with my invention, thepipe sections are strong and firmly held together.- The manner in whichI construct the buttress walls and insert and secure the ends of thedrain pipes within the walls provides a rigid buttress both for thesides of the roadbed and for the ends of the pipe sections.

The walls present-an extremely neat appearance, all portions of thewalls being flush on their outer faces, which renders them especiallydesirable as an ornamental feature.

My invention provides an extremely practical drain and the cost ofinstallation is such that it may be easily adopted by-townships andcounties throughout the different States which desire an extremelydurable and eflicient drain or culvert.

While I have described my invention as taking a particular form, it willbe understood that the various parts of my invention may be changed without departing from the spirit thereof, and hence I do not limit myselfto the precise construction set forth, but consider that I am at libertyto make such changes and alterations as fairly come within the scope ofthe appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:
